How Samsung DeX Works 2023 | Beginners Guide to Using the DeX

Here’s everything to know about how Samsung Dex Works? Check it out!

Android N’s Multi-Window mode has been extended to include Samsung DeX. Extra features and integrations with Samsung hardware, such as the Iris scanner, have also been added. 

As Samsung DeX is enabled by default, no proprietary Samsung APIs are required for the app launch. If an app follows Android’s best coding practices, it should work.

We’ll go over what Samsung Dex is, how it works, and some cool features, as well as some helpful hints for making the most of it.

What is Samsung DeX?

Multitasking is made more accessible with Dex, which extends the Android Multi-Window or Split-Screen mode.

The complete list of apps, an on-screen keyboard, and the ability to search for apps and items are all available in DeX mode. 

Take and send text messages, as well as make phone calls. DeX is not a desktop replacement in the traditional sense.

Because of this, it’s a companion that is less responsive than a standard desktop setting. Google Docs and Sheets can’t be opened simultaneously as on a laptop or desktop. 

Some people, such as writers, analysts, and financial professionals, may have a problem with this because browser extensions like ad blockers and password managers aren’t supported on DeX, it’s limited to mobile apps with less functionality.

Which Samsung DeX is the Best? 

How Samsung DeX Works

Several Samsung DeX and Samsung DeX on PC accessories and cables are available.

When using the platform, each line and adapter has different advantages. The DeX cable makes it simple to connect your device to a monitor with a standard HDMI port. 

The length of this monitor cable is 1.4 metres so you can use it with just about any monitor setup. This cable is ideal if you plan to use DeX in one location and can keep it connected to your monitor at all times. 

Corporate hot-desking scenarios frequently use this cable, allowing users to walk in, plug in their phone, and get to work.

Because there are no USB ports available, you’ll need to use Bluetooth peripherals instead. Use wireless charging if you plan to work for an extended period in DeX. 

The DeX multiport adapter provides the most significant portability when using DeX. In addition to the HDMI port, which connects to the HDMI cable on your monitor, you have a USB 3.0 port and a USB-C port for charging your phone.

Despite its small size, the multiport adapter can be easily carried in your pocket.

If you’re using a USB-C monitor, a USB-C to USB-C cable is an excellent choice. In this case, one end is connected to your device and the other directly to the monitor. 

Additionally, USB-C cables and monitors allow you to connect your wired keyboard and mouse to your monitor. While in DeX mode, it can also charge your device.

If you have a newer laptop with USB-C ports, you can also use a USB-C to USB-C cable to use DeX on your PC.

Alternatively, you can use a standard USB-C to USB-A charging cable for wired DeX on a PC. It’s very likely that you already have one of these for charging your electronic devices at home.

After removing the USB cable from its socket, simply plug it into an available USB port on your PC or Mac.

Samsung has also released a Smart Keyboard for DeX and the adapters. With the Bluetooth keyboard, you can easily switch between your Galaxy smartphone, tablet, and PC by pressing a single button.

How to Setup Samsung DeX?

The following instructions will guide you through the process of connecting your Galaxy smartphone and using DeX:

  • When using a DeX cable, plug it into the HDMI port on your monitor. Connect the HDMI or multiport adapter to the monitor’s standard HDMI cable if you’re using one.

  • Connect your mouse and keyboard. A Bluetooth keyboard and mouse will be connected to your computer using the HDMI adapter or the DeX cable. Turn on Bluetooth on your phone and search for your peripherals (typically involving holding down a Bluetooth button to make the device visible to your phone). If you have a USB 3.0 adapter, you can connect.

  • With the multiport adapter, you can also plug your phone’s charging cable into its USB-C port and your Ethernet cable into the adapter’s Internet socket.
  • Use the USB-C port on your phone to connect the adapter to your phone. Your monitor should display the Samsung DeX logo as it begins to boot up.

You can also refer to the official user manual for the DeX Station to learn how to connect and use DeX.

Tips on Using Samsung DeX

  • Activate the Developer Tools.

Unlike Android phones, Dex does not provide access to a Developer options menu. However, better app scaling is made possible as a result of this.

Many apps fail to expand to fill the entire screen, even when the Dex Lab’s force resizing option is enabled. 

Turn on developer options to make full-screen transitions less jarring. Keeping multiple windows open is easier when developer mode is enabled. 

Go to Settings from the Dex home page to do so. Go to Settings > About Phone > Dex and tap the Dex icon repeatedly.

  • Utilise keyboard shortcuts

The use of keyboard shortcuts is what really makes Dex convenient.

For example, you can open any browser app on your phone by pressing the Windows key + B or your contacts by pressing the Windows key C, or you can access all apps by pressing the ‘Windows key’. 

The screenshot above shows a list of Samsung Dex shortcuts. It’s not on the list, but it’s the one we can use most frequently. You can perfectly align two open apps using the ‘Windows key + arrow key’ combination. 

Maximising and minimising app windows can be accomplished by pressing the OS key + top and bottom arrows simultaneously. Press the Command Key instead of the Windows Key on Mac OS X.

  • Create Shortcuts for Common Tasks.

You can create shortcuts to various folders when you open the File app. Now it’s a whole lot easier to get to the folders you go to all the time.

Simply right-click (or tap with two fingers if you’re using your phone as a trackpad) on the folder in the Files app, and select the option to create a new shortcut.

  • Apps that are pinned to the taskbar

You can simply right-click on the taskbar icon and pin apps you frequently use. In addition, Samsung dex opens the currently active app (just one app).

  • Use your phone as a trackpad with Samsung Dex.

Once Dex is up and running, the notification shade contains an option to use your phone as a trackpad. The choice does not appear when you use a laptop or an external mouse to access dex; the option does not appear. The option will appear when your phone is connected to a brilliant display or monitor.

  • Adjust the font size, theme, and wallpaper.

Increasing the font size while using dex may be a better option. To do so, go to Settings>>Display and select the option.

The theme and font size can be adjusted in the menu, but most options are greyed out.

To change Dex’s wallpaper, simply right-click anywhere on the app’s home screen and select the ‘Change Wallpaper’ option from the context menu that appears.

  • Open a Social Media Browser in Your Device

Social media apps like Facebook, YouTube, and Instagram perform best in the web mode. Simply open your browser and switch to desktop view in the toolbar.

What can DeX do for your company?

How Samsung DeX Works

A single piece of technology that connects all of your employees and all of your business is a win-win for everyone.

It means having access to all the information they need on a single device without having to navigate multiple platforms or share projects and data between devices. 

To make things even more efficient, each team member can customize their device to meet their specific requirements.

Less expensive PCs and laptops are an obvious benefit for small and medium-sized businesses (SMBs). But more than just saving money in the short term, allowing employees more latitude in their workday boosts efficiency, communication, and overall output. 

DeX is even being used in vehicles to replace rugged laptops permanently attached to the vehicle in sectors like public safety.

This technology can also power complex mobile command centres on the scene of an emergency. Additionally, DeX provides security advantages. Biometric security and Samsung Knox safeguard Samsung smartphones and tablets.

Because it protects devices from the moment they’re powered on, the defence-grade security platform ensures the security of your data. 

Knox gives you powerful management tools, such as apps that allow listing and blocklisting, that you can use if you want to keep your company’s devices safe and secure.

For this reason, DeX is protected by all of these safeguards. Hackers have a smaller attack surface when there are fewer devices. 

For companies of all sizes, the benefits of mobile computing are already being felt in various industries, and they’ll want to get on board as soon as they can. DeX from Samsung is a ready-made solution with built-in safety.

How many apps can I use with DeX?

Apps like office suites, video-conferencing software, remote-desktop apps and even games are supported by DeX’s official app list.

Why does Samsung DeX have a hazy image?

Verify the display settings on your computer. It’s possible to adjust your display to work better with DeX if the programme doesn’t fill the screen or appears distorted.

Changing the screen fit options or disabling picture enhancements may be necessary if your display’s native resolution is lower than 1080p.

Can we charge the phone using DeX?

As soon as you plug in a charging cable to a DeX Station or DeX Pad, your phone will begin charging.

To wrap things up, 

DeX, aside from a few minor annoyances, is an excellent desktop platform. There’s no reason why DeX can’t be used in place of your laptop or desktop computer daily, assuming that the proper setup is in place.

Another benefit is that you don’t have to switch back and forth between your phone and laptop to access apps usually only available on your phone.
